Hello, Pit,
Thank you for contacting us and for using XStore.
If you want to change the type of your current tabs on the single products page, go to Single Product Builder > Tabs > https://prnt.sc/2m_gebadk7PO + https://prnt.sc/mRsZbzpsrpRJ
If you want to add a separate additional block. Create a new static block with the desired content inside https://prnt.sc/EwsuFudJ4Gh6 and show it on the single product page as in the example – https://prnt.sc/AUfMN-4gkzmh
We hope this information is helpful.
Kind Regards, 8theme team
